Colossus was a twin wooden roller coaster located at Six Flags Magic Mountain in Valencia, California, USA. It opened in 1978 as the tallest coaster in the world, along with Gemini at Cedar Point. Colossus was built by International Amusement Devices, Inc.


Colossus opened on June 19, 1978.

Colossus closed in late May, 1979. Coinciding with Six Flags' purchase of the park in June, the roller coaster was re-profiled, the trains were replaced with new ones from Philadelphia Toboggan Company and the brake system and some other mechanical components were replaced. It reopened on December 22.

In 1988, the PTC trains were replaced with rolling stock from Morgan. In 1991, the two camelback hills beside the parking lot were replaced with a flat brake run. This allows a higher theoretical capacity.

Colossus closed on August 16, 2014 after a 36-hour continuous riding event.[1] Much of Colossus' supports were used in the construction of Twisted Colossus.
